【Abstract】 Aiming at the influence of the size of the uncertain area on the system performance, based on the ground fixed point laser communication system, the initial pointing angle is obtained by coordinate transformation matrix, and the error factors affecting the accuracy of the visual axis pointing angle are analyzed. The Kalman filter technique is introduced into the visual axis pointing system to complete the system modeling.The experimental results show that the position data of GPS can be smoothed effectively by adding Kalman filter to the visual axis pointing system, and the prediction function of the filter can reduce the influence of dynamic lag and improve the accuracy of the axis pointing. It can reduce the size of uncertain area.更多还原
